CR123A 3V Lithium Battery
The PIR sensor relies on high-energy-density lithium chemistry to handle the burst current required for RF transmissions. Standard alkaline or low-quality cells suffer from voltage sag during transmit cycles, leading to premature low-battery signals even if capacity remains. High-capacity lithium cells ensure the voltage rail stays above the sensor's brown-out threshold during signal bursts.

Abode Motion Sensor (PIR)
If battery replacement does not resolve the issue, the internal Passive Infrared (PIR) circuit or the radio module typically has a hardware defect such as a leaky ceramic capacitor or a faulty Low-Dropout (LDO) regulator. This creates a parasitic current draw that depletes the cell during 'sleep' states, which are intended to be in the micro-amp range. As these components are surface-mounted and non-serviceable, the full sensor assembly must be replaced.
